The USB Isolator will isolate the power from the USB host (computer) and the connected device and provide a cleaner DC voltage for the USB device. The isolator will create a new ground for the USB device so that it doesn't have to share ground with your computer and other devices you might have connected in the same house.
This can be used to prevent ground loops. It will also protect the USB device and host from electrical shocks or static electricity shocks. It will also greatly improve the quality of the DC power signal used to power the USB device, which can improve performance of sensitive equipment like audio converters.
This Isolator doesn't require an external power supply. It features a isolated, regulated DC-DC module which is powered from the USB host (computer) and can give out 200mA, sufficient for commonly used USB equipment (but not all - check your device's power requirement!). Power is filtered with a LC filter featuring quality Sanyo OSCON caps.
It features a professional grade isolation chip, ADUM4160 and with an optimal layout it features signal isolation capability of 5000V and voltage isolation of 1000V. A low noise regulator is used to power ADUM4160 and low noise DC-DC converter gives a clean 5VDC power to the connected USB device.
USB Full Speed 12Mbps is sufficient for samples rates up to 96kHz/24bit. But it will not work with 192kHz/24bit samples rates as this requires USB "High Speed" 480Mbps (the is currently no chips available supporting USB "High speed")
Signal Isolation 5kV
Voltage Isolation 1kV
Built in 200mA power supply from USB bus (no external power supply required)
Power supply LC filter
ADUM4160 Support USB "full speed" 12Mb/s , but not "high speed" 480 Mb/s. Does not support USB low speed.
Size: 55x35mm + cable 10cm
